It's not a normal noise. This is not the starter or other starting only equipment. It's kind of a scrapping and squeal in the first .5 second till oil pressure is up. Could be other pump like steering or brake but I only get this when I start the engine after at least an overnight sit.
I wonder if it's the first seconds worth of oil starvation?
I don't know if these engines keep pressure on the filter as some cars do to reduce time to prime and pump oil at start-up.
I don't like the sound but not much to do about it.
